We stayed in the Garden House, which is located at the base of the property. It doesn't have the elevated views of the other accommodations, but it's more private and secluded, has a large wrap-around veranda, and is steps from the Botanic Garden. It's more rustic than it looks on the website pics, and the futons in the pictures were regular mattresses made up as beds, so there wasn't really any seating other than the barstools. The kitchen included a microwave, coffee maker, and bottled water dispenser that was replaced when empty. I suggest stopping in San Ignacio on your way for groceries/snacks, since the road to the resort is narrow and bumpy- not a trip you'll want to take multiple times.
The resort itself is built on the river bank, with everything accessed by walkways with steps/stairs, so not a good choice for anyone with mobility issues. But everything is well-maintained, and the pool and restaurant are lovely. The food was very good, and we took the resort shuttle to dinner one night at the nearby Chaa Creek resort, just for a change of scenery.
The website mentions extensive hiking trails, but when I asked about a map/locations, I was told the only thing we could do on our own was the river tubing trail loop. Everything else required a guide. We did enjoy strolling around the Botanic Garden, but I had hoped to do more hiking.
The thing that stood out the most about the resort was the wonderful staff- everyone was hard-working, friendly and helpful!
